The Federal Aviation Administration (FAA) building in Longmont, Colorado was undergoing renovations and there was concern over striking conduits  or pipes in a concrete wall when saw-cutting. The contractor who was in charge of the site was told that traditional concrete radiography would not work in this situation due to the thickness of the wall being greater than 12”. Ground Penetrating Radar Systems of Denver was able to mobilize to the construction site and keep the project on schedule. One conduit was located along the bottom of the wall and marked for the safety of the saw operator. Also while on site, the GPRS technician was able to map out the rebar pattern and structure for the FAA facilities team for future reference.

GPRS is used often in situations where x-ray will not work. In this case, the concrete wall had a thickness of 18” which is no problem for Ground Penetrating Radar Technology because of the ability to scan on both sides of the wall.
